In a bid to save the Great Indian Bustard (GIB), currently on the brink of extinction, Indian government’s Ministry of New and Renewable Energy (MNRE) has asked wind power developers to identify the bird’s critical habitats in Rajasthan and Gujarat and take risk mitigation measures against bird hits, one of the causes of the reducing population of the bird.
The lease of an offshore wind power project can be cancelled if it is found to be “causing environmental damage to both flora and fauna beneath the sea and posing threat to human life and property while carrying out the activities under water and operation of the wind energy turbines during validity of the lease.” The draft rules also contemplate powers to the Centre to order closure of a wind farm pending an inquiry within a reasonable period if it finds “operation of the wind turbines is causing damage to environment or damage to property or pollution.”
Li said: "The challenge could be the potential curtailment due to limited transmission space and a saturated Beijing-Tianjin-Hebei power market. "If curtailment can’t be solved, the profitability of the projects will be a concern."
The feed-in-tariff needs to reflect the extraordinarily high costs faced by Greater Changhua 1 and 2a, mainly related to creating a local supply chain at scale, reinforcing the onshore grid infrastructure and building, operating and maintaining offshore wind farms in challenging waters where typhoons and earthquakes occur.
The Ministry of Economic Affairs yesterday cut the preliminary feed-in tariff for offshore wind energy developers over the next 20 years by 12.7 percent due to falling installation costs, dealing a blow to developers that were expecting it to remain the same.
Study coauthor Professor Maria Thaker said: 'We have known from many studies that wind farms affect birds and bats. 'They kill them and disrupt their movement. But we took that one step further and discovered that it affects lizards too. 'Every time a top predator is removed or added, unexpected effects trickle through the ecosystem.
In new research, an international team of scientists studied the effects of wind turbine use in the Western Ghats, a UNESCO-listed range of mountains and forest spanning India's west coast region and a global "hotspot" of biodiversity. They found that predatory raptor birds were four times rarer in areas of plateau where wind turbines were present, a disruption that cascaded down the food chain and radically altered the density and behaviour of the birds' prey.
Vestas said a nacelle detached from the tower and fell to the ground together with the blades at one of the company’s V136, 3MW machines at Wind Energy Holding’s 60-turbine T2 and T3 wind farm in Nakhon Ratchasima and Chaiyaphum provinces. ...The towers have a hub height of 157 metres.
“At present, we are considering a method of removal because the maintenance cost is too high,” the government source said Friday. The turbine is one of three on a floating wind farm 20 km off the coast of Naraha.
Due to concerns about earthquakes, typhoons and other natural disasters in Taiwan, European insurers estimate that insurance premiums for Taiwanese wind farms will be at least 30 percent higher than those for European offshore wind farms, Lin said. In addition, government-imposed local content requirements in Taiwan would also prompt European insurance companies to raise their risk assessment for local wind farms and thus the premium, as they do not consider the local supply chain mature.
Built in 2002, the turbine had been out of commission since May last year after being struck by lightning, according to the Japan Times. News footage showed how the turbine had been torn from its base by the strong winds, with its 20-meter-long blades badly damaged by the impact with the ground.
The giant windmill was found to have collapsed at around 6 a.m.. Parts of it had fallen onto a road that runs alongside the park.
Revenue fell to Rs 1,277.49 crore versus Rs 2,581.99 crore.
In a blow to a region hit hard by the Fukushima nuclear disaster, offshore floating wind turbines being operated on a trial basis here are producing much less electricity than initially anticipated. The disappointing output so far is casting a shadow over the government-backed project.
Chinese wind turbine maker Sinovel Wind Group Co was convicted on Wednesday of U.S. charges that it stole trade secrets from AMSC, causing the Massachusetts-based company to lose more than $800 million. A federal jury in Madison, Wisconsin, found Sinovel, once AMSC’s largest customer, guilty on all charges it faced, including conspiracy, trade-secret theft and wire fraud, the U.S. Justice Department said.
The committee heard testimony last week that the rotating blades of the nine 540 ft. tall turbines could decimate the red falcon population in the area.
Much of the country’s renewable energy supply is currently subject to double-digit rates of curtailment. This curtailment has been going on for quite some time, leaving many of China’s clean power systems seeing little use. It has also highlighted longstanding problems with the country’s aging energy infrastructure.
Around 0.09 per cent of ALRO land – or about 3,695 rai (591 hectares) of a total 41 million rai – has already been used for these undertakings as per NCPO order 31/2560. The order has been criticised by land activists, academics and farmers who see it as an attempt to seize land preserved for landless farmers in order to top up the wealth of energy and mining conglomerates.
Three companies want more than 70 turbines to go up, but the ministry says residents’ ears, the landscape, birds and bats would suffer as a result; The ministry’s opinion relies on a paper by the companies themselves. The ministry says 13 of the turbines would be less than 500 meters from homes, which conflicts with the recommendations of both the environmental protection and health ministries because of the noise.
Deserts, often considered wastelands, are crucibles of spectacular wildlife, but they are threatened by India’s ambitious renewable energy generation target of 175 GW by 2022. The ecological footprint of an individual wind turbine or solar panel might be negligible, but massive wind or solar farms require huge swathes of land. Roads are constructed to lug turbines, and earthmovers rip through forests or grasslands, permanently altering the landscape.
